Isoxsuprine
Isoxsuprine is in a class of drugs called vasodilators. Isoxsuprine relaxes veins and arteries, which makes them wider and allows blood to pass through them more easily.
These actions may help treat the symptoms of conditions such as cerebral vascular insufficiency (poor blood flow to the brain), arteriosclerosis (hardening of the arteries), Raynaud’s phenomenon, and other conditions involving poor blood flow in the veins and arteries.
Isoxsuprine may also be used for purposes other than those listed in this medication guide.
